When you get that repeated prompt for username and password, click Cancel,
which should then produce an error message. Right-click on your error message,
copy, then paste it into a reply here. We can't do much troubleshooting without
the complete error message.
First, test your password by logging in to your provider's webmail:
If that works, it proves you have the correct username and password.
A likely reason for the username/password failing in Windows Mail is
account corruption. One thing you should try as a possible quick fix is
to delete that corrupted mail account, restart Windows Mail, then
recreate that account.
If that doesn't fix it, more drastic measures will have to be taken.
Which antivirus are you running?
As a minimum, email scanning in the antivirus must be turned off,
although that may not be sufficient to eliminate all bad effects.
In a worst case scenario, your antivirus may need to be uninstalled.
